CONTAINER, FOR DISPENSING MATERIALS Filed Sept. 17, 1937 2 Sheets-SheetZ Patented Apr. 4, 1939 UNITED STATES PATENT OFFICE ApplicationSeptember 17, 1937, Serial No. 164,297 In France September 80, 1936 18Claims. (01. 221-) The invention relates to a container for dispensingmaterialscomprising a permanent portion and a deformable flexibleportion which is pushed progressively inwards up to the inner wall ofthe permanent portion to dispense the contents of the container.

Containers for dispensing materials have already been proposed whichcomprise a permanent portion and a deformable flexible diaphragm, butsuch containers are useless in practice, either because their diaphragmsare not suificiently protected, or because the means proposed forassembling the two portions are very costly or very diflicult to apply.

The present invention has for its object to avoid these drawbacks bymeans of a dispensing container comprising a permanent portion providedwith an'outlet nozzle, a deformable flexible diaphragm and at protectingskirt.

According to a first embodiment, the three component elements of thecontainer, viz: the permanent portion, the flexible diaphragm and theprotecting skirt are assembled together in a single crimping ring.

According to other embodiments, the protecting skirt which is removableor not, is fixed on the container by clamping, screwing or any othermeans. The permanent portion can be held in shape either by the rigidformation of its wall, or by a rigid outer cap. The cap and theprotecting skirt as a whole can form a case in which is arranged thecontainer which forms a refill cartridge.

The invention further includes a container the deformable portion ofwhich comprises bellows.

Several embodiments of the invention are illustrated in theaccompanying? drawings by,

way of example.

Fig. 1 shows a container wherein the protecting skirt is fixed;

Figs. 2 and 3 show containers having removable protecting skirts;

Figs. 4 to 6 show containers provided with a lid forming a stopper;

Figs. 7 to 10 show different embodiments of containers arranged in acase;

Fig. 11 shows a container wherein the deformable portion comprisesbellows.

The dispensing container shown in Fig. 1 comprises a permanent portion Iprovided with an outlet nozzle 2, having a stopper 3, a deformableflexible diaphragm 4 and-a protecting skirt 5. The three parts areassembled together at 6 by a single or repeated crimping.

The container can be made of tin, aluminum,

paper, metallized paper, plastic material, transparent or translucentmaterial orany other appropriate material. The assembly of the threecomponent parts by crimping permits of very low production costs andthereby ensures a very 5 great economy relatively to the known containers. Furthermore, the protecting skirt enables the container to be heldmore conveniently in the hand, ensures the perfect preservation of itsouter shape and consequently its stability. The filling 10 of thiscontainer is most advantageously eifected in the following manner; Theflexible diaphragm is arranged before filling against the inner wall ofthe permanent portion and is turned inside out by the pressure of theproduct introduced 15 through the nozz'e. To cause the contents of thecontainer to come out, it suffices to press the flexible diaphragm 4with the thumb or a finger, and said flexible diaphragm willprogressively take up the inside shape of the per- 20 manent wall I.

The removable protecting skirt 5 shown in Fig. 2 is held on the crimpingring 6 of the two caps by merely forcing, owing to its slightly conicalshape. geously provided with a flange or a recess to ensure a firmer fitof the removable skirt which could be fixed by any other known meanssuch as screwing, bayonet closure, etc.

The crimping ring will be advanta- 25 The dispensing container shown inFig. 3 com- 30 prises two parts i and 4", each provided with a fiatcollar 1 and 8, the two collars being held together by a protectingskirt made in two parts 9, In which screw or fit firmly into each other.i

This container can be delivered in separate parts for assembling by theuser or by the retailer after the two caps have been filled. Thepermanent cap I can be made of rigid or of flexible material; in thelatter case it is held 4 in shape solely owing to its being fixed to theprotecting skirt.

According to the embodiment shown in Fig. 4, the protecting skirt 5,which is fixed on the ring 6, is provided with a screw thread ll,permitting (5 of the fixing of a case I 2 forming a cover and having-acorresponding thread I3, shown in the drawing, or the fixing of a caseprovided with a nozzle.

Fig. 5 shows a container assembled by crimping to a protecting skirt 5,the assembly being arranged in a case formed by an outer protectingskirt l4 fixed by means of a clamping ring 15 and having a cover I6.This embodiment enables the cartridge to be transported without 56packing and optionally without a removable stopper.

According to an embodiment shown in Fig. 6, the permanent portion of thecontainer is provided with ribs I'I. 0n said ribs I1 is fitted theclosure l8 forming a cover. The ribs have the advantage of reinforcingthe permanent portion. The ribs can be replaced by nipples, or by ascrew thread or the beginning of a screw thread formed on the permanentportion.

In order to obtain an easy and efficient fixing of the stopper forming acover so that same can be readily fitted or removed, the following meanscan be employed: a stopper forming a cover having a resilient wall on acartridge having a rigid wall; a stopper forming a cover having a rigidwall on a "cartridge having a resilient wall; a stopper forming a coverhaving a rigid wall on a cartridge likewise having a rigid wall butprovided with resilient ribs.

The dispensing container shown in Fig. 7 has a case formed by a cap l9carrying the nozzle 20 provided with a stopper 2| and secured byscrewing to a protecting skirt 5.

In this construction the container forming a refill cartridge containingthe product to be dispensed, comprises an upper cover l9 provided with anozzle 20 and secured to the deformable diaphragm 4 by crimping at 6.The cartridge is held stationary in the case by clamping its crimpingring 6 between the upper cover l9 and the protecting skirt 5. To reducethe height of the protecting skirt, the deformable diaphragm can have aconcave central portion 22.

In Fig. 8, the upper cap l9 and the protecting skirt 5 are integral. Thenozzle 20 of the case is internally threaded and serves for assemblingthe case to the threaded nozzle 2 of the cartridge.

Fig. 9 shows a container comprising a permanent portion i provided witha nozzle 2 and secured to a deformable fiexiblediaphragm 4. A protectingskirt 5 is mounted by means of a clamping ring l5 on the crimping ring6. On said clamping ring is fixed a cap l6 secured to the nozzle 20. Theclamping of the ring i5 is ensured by projections 23 arranged on theskirt and the clamping of the cap I6 is effected by projections 24arranged on the ring l5, or by any other known means, for examplescrewing, clamping, bayonet joint, etc.

Fig. 10 shows a dispensing container provided with a tubular nozzle 25enabling the container to be used as an oil can. The nozzle can be fixedon the case or, as shown in the drawings, screwed on the threaded nipple2 of the cartridge, so that the case I6 is clamped between the permanentportion I of the cartridge and the collar 26 of the nozzle 25.

The invention furthermore includes two novel constructions of the refillcartridge. In Fig. 10, the deformable portion of the cartridge is partlyformed by bellows 26 having concentric elements. In Fig. 11, thecartridge is formed by a permanent cap I which is closed by bellows 21or by a deformable diaphragm. This cartridge can be employed incombination with the various cases described above.
